4.6 Santa Barbara earthquake woke people, but no damage reported

There were no immediate reports of damage or injuries after a magnitude-4.6 earthquake shook the Santa Barbara coast Wednesday morning, officials said.

The temblor struck at 7:38 a.m. about three miles west of Isla Vista, the U.S. Geological Survey reported. Initial reports indicated that the quake had a magnitude of 4.9, but that was later adjusted to 4.6.

Two magnitude-2.6 aftershocks -- one in the same spot at 7:50 a.m. and another a mile west at 8:38 a.m. -- were also recorded, the USGS website reported.

The Santa Barbara County Sheriff's Department, Office of Emergency Management and Fire Department said they had no initial reports of injuries or damage.

A spokesman for UC Santa Barbara -- located in Goleta -- said preliminary information indicated that there was "no damage at all."

"No damage reported in the area," said Michael Dalcerri, captain at Santa Barbara County Fire Station 17 on the campus. "We pulled our rigs out, checked the area -- campus area, Isla Vista -- no damage to report."

Dozens of people stretching from Bakersfield to Manhattan Beach reported feeling the quake on the USGS "Did you feel it?" site.

A man who answered the phone at the Santa Barbara Inn called it a "slight shift," but said there was "no big reaction" from guests.

Goleta resident Lisa Green told KTLA that her house "was just rocking back and forth, back and forth." A few pictures fell off the wall and her medicine cabinet flew open, she said.

"My dogs were going crazy," she said.

After the shaking subsided, Green said, her neighbors went outside to check on one another.

Others reported the quake on social media.

"I live in IV and it woke me up!" @ahhhlexx15 said. "But it wasn't scary if you know earthquakes."
